You're not crazy! Post #45 was related to the sear and the action of the lobe of a thumb safety, that's why I posted what I did. It appears DevilDave1911 caught it and edited. Good job, DevilDave1911.

Either a Clyinder and Slide with mic's up at max .200 and is made from a forging. The second best I feel is EGW. which also is machined and mic's up to .2000 also.
I trust my life with these and they have been put in all my 1911's.

If anything is "sticky quality" it's this one. And, it oughta be in the "How To" forum as well since this is such a critical part to fit absolutely correctly. Also, when moved, the title should probably be changed to "Critical Info Re: Fitting Thumb Safety's & S80 Trigger Jobs" since critical things about the latter are also addressed in the same thread.

Best,
Jon

Congratulations on your Canon! My favorite brand of camera. Now, to slide stops. I encountered a breakage of a Colt slide stop as you describe in your picture. It was 10 degrees out when the break occurred, however, I felt it should not have broken.

The following is what I have posted on another thread, but perhaps you will have some comments on the issue I have been encountering:
Over the years, I have encountered to some degree or less, a problem with the 1911 magazine not pushing up the slide stop to lock the slide open after the last round has been fired. When this happens the magazine follower slips over the slide stop, making the magazine difficult to remove from the gun. I had been told by a gunsmith that I needed extra power magazine springs. I tried them, and that did not fix the problem. I replaced the slide stop, and that did not fix the problem. For some reason which I do not recall, I determined the problem was with the slide stop. I bought two more slide stops, and one of them fixed the problem. Any magazine I use will push up this slide stop to lock open the slide. Now, this slide stop protrudes over the magazine follower about an additional 1/32 inch more than my other slide stops do. I bought this slide stop at a gun show, and do not know where to find another one like it. I would like to buy another 1911 slide stop that protrudes about an additional 1/32 inch more over the magazine follower, than the standard size slide stop. Anyone out there know where I can find it?

I came across a website that explains the problem I have been encountering, better than I explained it. Here it is: http://ezine.m1911.org/metalform.htm

Any word on Springfield slide stops?

The ones I have pulled from a few new Springfields seem to look just like the Ed Brown HC one you posted and the same as the EB HC ones I have floating around.

I have the problem of the magazine follower occassionally slipping over the slide stop after the last round is fired with my Springfield.

I'm not too good with a computer. How do I send pics ? I use a MAC.

I tried the EGW stop and it didn't work. I got an Ed Brown and it didn't work either. I did find that there are different sized lobes on different stops, depending if they are specifically for .45 or for .38/9mm. You can gradually work the proportions of the bigger one down until it works better. This still didn't eliminate my mag problems. I finally ordered a #19-B stop from Fusion. This one worked perfectly. I ran my 5 Wilson mags through my pistol several times and no malfunctions. The problem seems to be fixed. Thanks to pistolwrench and the rest of you guys for some very valuable information.

[Caspian17]

Fusion is just a Wilson, Ed brown or STI part in a new bag... so maybe you just got over-sized parts like Wilson and Ed brown say you may have to fit.

[jfrey]

Fusion lists 2 different numbered slide stops. The 19-D has the larger lobe like the EGW and Ed Brown. The 19-B has the smaller lobe like the stop in my Briley Commander pistol. Who ever actually makes them, the 19-B stop seems to have cured my problems and I am a happy shooter for the time being. With a life time warranty and no apparent flaws that I can find, I think I'll keep using them until I find something I like better.

If you were having mag problems, why were you messing with the slide stop to fix it? That is, I could never get the slide to lock on Wilson mags, and found changing to a different brand of mag fixed the problem.

What a great thread! Thanks!!! Now, can we get one about beavertails?

[tracyballard]

great info, it's helped me settle on an Ed Brown hardcore slide stop. now, if I can just get my Fuji finepix to take pictures like that...

[gettheroof]

What brand is the "major manufacturer" MIM part?

Is that taboo?

Happened to me also, right in the middle of a course. POS...

Taken from the pages of Ed Brown, nothing about bar stock only guarantee.

So tool steel can be investment cast. I assumed otherwise.

Boy is this stuff interesting!

[scalinghammer]

Yes tool steel can be cast. The following links to US investment casting sources should d2 s7 and a2 all good tool steels.

The second link is not really tool steel. It is a part they made for us 40 years ago. I still have it made just not by them.

I have a question,

I had to tweek a slidestop and put some black marker on the grind.
Do i need to do a more thorough rust proofing of this part.
What is the least complicated and least expensive (not cheap) method for touching up un-seen areas.
I don't want to bake gunkote on a 5mm patch if i can spray rustoleum (for example)on it.

Augisimo

[Magnumite]

cold blue it for those unseen areas.

I saw the slidestops, they don't have my issue. mine was a sparepart i bought for my pistol from a competitor, it had a deep shoulder on the bottom, under
the lug, just needed to raise the stop a tad.
I just thought with so many people putting the logman improvised plunger
tickler on their SS, I would think the bare metal needed some covering.
I did see the one broken pin was on a thumb safety, looks like it fell out of a run away toyota.

[191119111911]

I just picked up 2 EGW HD Slide stops and one HD Thumb safety. They are supurb! One Wilson 47D would not lock back the slide on another 1911. The 1911's with Geo's stop both lock back the slide with the problematic mag.

Here is a picture of a Taurus hammer strut (MiM) on the left and a Cylinder and Slide hammer strut next to it. The difference is not so subtle.

[reyesah]

WOW these pictures are great! where are you guys buying these cameras.
